为了探讨在听复杂听觉刺激时伴随情绪配价判断的神经生物学机制，记录了16名右撇子学生的皮层直流电-脑电激活模式。学生们听了从爵士乐、摇滚乐、古典音乐和环境音乐曲目中摘录的160个短片段。声音(每组n=40)。在每个序列之后，对感知到的刺激的情绪效价进行5级量表评级。大脑在倾听过程中的激活模式显示了广泛的双侧额颞叶激活，但有一个非常显著的偏侧化效应：积极的情绪归因伴随着左侧颞叶激活的增加，负面的是更多的双侧模式，右侧额颞叶皮质占优势。女性参与者比男性参与者表现出更大的价态相关差异。没有发现与四种刺激类别相关的差异，这表明实际的听觉大脑激活模式更多地由它们的情感情绪价位决定，而不是由听觉“精细”结构的差异决定。这一结果与海尔曼提出的关于感知积极或消极情绪的大脑半球专门化模型是一致的[《神经精神病学和临床神经科学杂志》9(1997)439]。(C)2002爱思唯尔科学有限公司。保留所有权利。
In order to investigate the neurobiological mechanisms accompanying emotional valence judgements during listening to complex auditory stimuli, cortical direct current (dc)-electroencephalography (EEG) activation patterns were recorded from 16 right-handed students. Students listened to 160 short sequences taken from the repertoires of jazz, rock-pop, classical music and environmental. sounds (each n = 40). Emotional valence of the perceived stimuli were rated on a 5-step scale after each sequence. Brain activation patterns during listening revealed widespread bilateral fronto-temporal activation, but a highly significant lateralisation effect: positive emotional attributions were accompanied by an increase in left temporal activation, negative by a more bilateral pattern with preponderance of the right fronto-temporal cortex. Female participants demonstrated greater valence-related differences than males. No differences related to the four stimulus categories could be detected, suggesting that the actual auditory brain activation patterns were more determined by their affective emotional valence than by differences in acoustical "fine" structure. The results are consistent with a model of hemispheric specialisation concerning perceived positive or negative emotions proposed by Heilman [Journal of Neuropsychiatry and Clinical Neuroscience 9 (1997) 439].
